Except we can't use clone2() because it conflicts on ia64. Care to proposea name you would prefer?

Also I was a bit suprised to discover there are plenty of examples where thisconvention has not been followed: vm86, lseek64, and mmap2 to name a few. Infact, of the 46 __NR_foo[[:digit:]]+, 36 break this convention on x86-32.
